other and in spaced relation to the side walls of the recess or casing.And since it is desirable to utilize all of the cross sectional area ofthe interior of the casing or the radiator, the opposite ends of theradiator are usually arranged in close proximity to said side walls ofthe recess or casing which thus arranges the ends and the inlet andoutlet of the radiator at one side of or beyond the ends of the risersentering the casing which necessitates employing a special fitting toconnect these openings with the risers. It is an object of the inventionto provide a radiator which substantially fills the above mentionedspace and which eliminates the necessity of special fittings to completea connection between the radiator and the risers.

Another object of the invention is to provide a radiator. capable ofresulting in the above mentioned advantages in which heat radiatingmeans is located between the risers and also between the end walls ofthe recessor casing and'said riserswith the inlet and outlet openings ofthe radiator in substan tial alignment with the risers. Another ob jectof the invention is to construct the means which extends between the endwalls and the risers so that air may circulate therethrough, be heatedthereb and enter the recess or casing and be su sequently discharged ina heated condition therefrom.

Another object of the invention is to provide a structure such as abovewith means through which the heating medium is introduced to the device,said means having a por- 50 tion thereof located in a manner which willprevent condensate from interfering with the introduction of the heatingmedia.

The invention has these and other obf'ects all of which will beexplained in detai an more readily understood when read in conjunctionwith the accompanying drawing which illustrates a means foraccomplishing the above enumerated advantages, it being manifest thatchanges and modifications may be resorted to without departing from thespirit of the appended claims forming a part hereof.

In the drawing, Fig. 1 is a sectional view of a portion of a wall havinga recess provided therein in which the radiator is located, the recesshaving openings whereby air maybe introduced to the heat exchange deviceand be discharged from the recess in a heated condition;

Fig. 2 is a sectional 2-2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a sectional view showing a detail of construction employed inthe device.

In the structure illustrated in Fig. 1, a recess 10 is formed in a walland when so desired, a metallic casing 11 may be mounted within therecess. The casing 11 has aremovable front wall 12. A grilled opening 13is provided at the upper portion of the casing through which heated airmay be discharged from the casing. The casing 11 has an opening 14adjacent the lower end thereof and a radiator unit 15 is located in thelower end of said casing and above the opening.

By referring to Fig. 3, it will be noted that the radiator unitgenerally designated 15 is view taken on the line 70 ,in communicationwith risers 16 and 17 and therefore heating media may be supplied to theradiator. Under ordinary conditions, the ends of these risers'16 and 17are spaced a standard or prescribed distance from each other and arealso spaced a certain distance from the end walls such as 18'18 of therecess. Since it is desirable to completely fill the cross sectionalarea of the recess or casing, the tanks or manifolds generallydesignated 19 and 20 of an ordinary structure are arranged in closeproximity to the end walls 18-18- which arranges said tanks ormanifoldsat one side of the risers between the risers and the end walls,this arranges the inlet and outlet openings of the tanks 19 and at oneside of the risers, which would, therefore, require a special fittin tocomplete the connection between the tan s 19 and 20 and the risers.

To eliminate the necessity of these special fittings, the inventioncontemplates arranging the tanks 19 and 20 a distance from each othersubstantially correspondin to the distance between the risers 16 and 1which will thus permit the radiator unit to be directly connected withthe risers 16 and 17 without the necessity of special fittings.Theinvention also contemplates the provision of means whereby the spacebetween these tanks 19 and 20 and the end walls 18 may be utilized toheat air entering and circulating through this. To this end, it iscontemplated to space. provide each of the tanks 19 and-20 with heatradiating fins respectively designated 21 and 22 which may be formed ofseparate sheets of material attached to the header ontanks,

or may, as shown at 23, be constructed to provide hollow extensions 25which'are spaced from each other as indicated at 26 to provide airpassages between said fins. The radiator tubes 15 as before statedextend between the 'tanks and form a communication therebetween andthese tubes are provided with heat radiating fins 27 which in effectprovide open ings between the tubes and the fins through which air maypass and contact with the tubes and fins and heat the air as itflowsthrough the opening into the casing 11.

As before stated, the invention contemplates the provision of a meanswhereby any accumulation of condensate taking place within the radiatorwill not interfere with the supply of heating media to the radiator.

To. this-end, the inlet opening or the supply riser 17 is provided witha nipple 28 which extends into the tank- 20 and terminates a suitabledistance above the lower portion of the tank or in other-words above theliquid level of any condensate which may accumulate therein. From thisit can be seen that construction is provided which will allow.

,the unit tobe connected with the risers 16 and 17 without the necessityof special fithugs to compensate for the difference of distance betweenthe risers and inlet and outlet openings of the tanks such as 20 and anda aseasai through causing same to flow upwardly relatively to the recessor casing 11 and be disa charged through the outlet opening 13 providein-the casing. By means of the removable wall 12 access to the unitandthe fittings connecting the unit with the risers may be had in theevent replacement or repalr is found necessary.

Having thus described the invention, what I claim as new and desire tocover by Letters Patent isi I 1. In a radiator the combination of tanks,and tubes arrangedat one side of and connecting said tanks and hollowfins arranged upon the opposite side of said tanks and connected withsaid tanks, one of said tanks hava fluid inlet and a fluid outlet.

3. Ina device of the kind described the combination of a wall having arecess, a heat exchange device located in the lower. portion of therecess in spaced relation to the lower end thereof, said heat exchangedevice being extended transversely of the recess and including fluidconducting. tubes and means connecting said tubes arranged transverselythereof and in spaced relation to the end .walls ofthe recess and hollowheat radiating fins arranged between said walls and said means saidhollow fins opening into said means. L

4. In a deviceof the kind described the combination of members eachhaving an openin respectively roviding a fluid inlet fluid outlet, andhaving a plurality of openings provided in' one side of said members andtubes providing fluid passages connected with said openings and hollowfins arranged along said members and transversely of said members uponthe side of said members, opposite to that side having said plurality ofopenings.

In witness whereof, I hereunto subscribe 11g name'this 4th day ofDecember A. D.,
